Question

Pls help this question I am really struggling with

Answer 1

A = 3 , B = 9

Explanation:

to find A and B substitute the values of x above A and B into y

x = - 1

y = - 2(- 1)² + 4(- 1) + 9 = - 2(1) - 4 + 9 = - 2 + 5 = 3

then A = 3

x = 2

y = - 2(2)² + 4(2) + 9 = - 2(4) + 8 + 9 = - 8 + 17 = 9

then B = 9
